well i had a couple questions 1. is there anything extra you need to hook the speakers up? 2.what speakers are good for the money? 3.are the expensive speakers worth the more money then getting cheaper speakers like kicker speakers?

Yes you will need an amp for tower speakers. The Headunit does not provide enough power for the speakers. But for an amp it all depends on the speakers. Lets say you have 100 watt rms speakers or maybe higher, like the wetsounds for instance. You will need at least an amp that can produce 100 watt rms to each speaker.
